So I'd say about a month **Q: Is this concentrated? If so, how many gallons of water do you add?** A: It is concentrated and you don't dilute it, the spray bottle system delivers the right amount with your hose water pressure (if it works well). Should take 30-40 minutes to apply. **Q: will this kill my new seed they have not sprouted yet?** A: No, it won't kill your new seed -- in fact it will help establish them. All of the Simple Solution products do not burn and are in concentrations that are beneficial in virtually all cases. I have used most of them for a few years and they seem to be the best lawn products i have found. **Q: I killed/scalped/detached weed-infested lawn and plan to slice-seed new tttf tall fescue. when before/after seeding should i apply this? (san diego)** A: Apply after seeds have sprouted. Best if sprayed with a sprayer that you can pre mix the water then spray. ## Frequently Bought Together - Extreme Grass Growth Lawn Booster- Liquid Spray Concentrated Starter Fertilizer with Humic - Any Grass Type- Simple Lawn Solutions (1 Gallon) - Advanced 16-4-8 Lawn Fertilizer - Liquid Lawn Food Spring & Summer Concentrated Spray - Any Grass Type- Fish and Seaweed Kelp- Balanced NPK - Simple Lawn Solutions (1 Quart) - Liquid Soil Loosener- Soil Conditioner-Use alone or when Aerating with Mechanical Aerator or Core Aeration- Simple Lawn Solutions- Any Grass Type-Great for Compact Soils, Standing water, Poor Drainage --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/519007971-extreme-grass-growth-lawn-booster-natural-liquid-spray-concentrated-fertilizer](https://www.desertcart.hr/products/519007971-extreme-grass-growth-lawn-booster-natural-liquid-spray-concentrated-fertilizer) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-11-11*
